APPARATUS EOE CONSTEUCTING THIN CONCRETE WALLS AND EEEOTING THE SAME.

Application filed April 18, 1925. Serial No.' 24,173.

To all whom it may concern.'

Be it'known that I, JOHN M; SARGEANT, a citizen of the United States, residing'at Elmira, in the county of Chemung and State of New York, have 'invented certain new and'useful Improvements in Apparatus for Constructing Thin Concrete Walls and Erecting the Same,of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to `apparatus for constructing thin concrete walls and erecting the same and more particularly to a device for casting "the walls in position over afbase upon which the walls are to be erected.

An important object of the invention is to provide a device of this character permitting casting of the wall in a horizontal position and casting of all of the walls of a building at the same time.4

A still further object of the invention is the provision of a device of this `character including a pivoted platform upon which the wall to be cast is formed and supports for the platform about which the platform may be pivoted to bring the same into proper .relation to the base together with means permitting the mold to be moved'directly over the base for the casting operation in event there is some obstruction adjacent the base such as a tree, another building or the like which will prevent the casting from being formed in what is its normal position or the position where the form is supported above the base in such manner that when rotated `upon its supporting aXis,the wall is properly positioned above the baseand need only be lowered in the proper position.

A further object of the invention is to provide a structure of -this character in which a'widev range of adjustment may be `had permitting the use of the device for casting walls of varying dimensions.

A still further object of the invention is to provide means for applying to the mold after the cementjhas been deposited therein a jarring action whichwill cause the cement to be freed from bubbles and assure a .finished smooth surface on the completed wall.

These and other Objects'l attain by the constructionl 4shown in the `accompanying drawings, wherein for the purposevv of illustration is shown a preferredembodijment of mi* intenti@ and wheeinzee assort Figure 1 is a side e eva ion of apparatus constructed in accordance with my invention in the position which it occupies during the time that the casting is being effected;

Figure 11 is a detailed view showing the type of joint which will be employed in joining the walls after the formation thereof.

' Referring now more particularly to the drawings, the numeral 10 designates a base. Such a base. with which the apparatus is to be employed in the process of formation therein has embedded bolts 11 protruding` above the base at each corner and bolts 12 protruding through the side of the base at each corner and having aA predetermined position with relation to the bolts 11. These bolts are adapted to extend through slots formed in horizontally and vertically eX- tending flanges 13 and 14 of a post socket or retainer 15' so that this socketland the circular post 16 which it supports may be rigidly secured to the base. A socket 15 and post 16 are arranged at each corner of the base. The post 16 is provided adjacent its upper end with vertically spaced horizonta-llv directed openings 17 for the reception of a `retaining pin 18, the purpose of which will soon become obvious; f

' 'Mounted upon Veach post adjacent the lower end thereofis -a journal casting 19 inlLi CII

cluding a vertical tubular boss 2O split and eared at one side, as indicated at 21, so that it may be clamped in both vertical positions and in a rotatably adjusted position upon the post. Each journal casting has projecting from opposite sides thereof bea-rings 2Q, Q3. The bearing Q3 is notched, as at 24;, to provide two sections-having bearing grooves forthe reception of a shaft 26 at opposite sides of a ratchet wheel 2T secured to the shaft. Pivoted to the journal casting above the notch is a dog 28 for coaction with the ratchet wheel 2l'. Upposite ends of the shaft 26 are squared, as at 28, for the reception of a wrench 29 by means of which the shaft may be rotated. The shaft has additionally secured thereto a pinion 30, the purpose of which will presently appear.

In applying the journal castings 19 to the post 16, they are arranged in pairs, the bearings 22 of each pair aligning for the reception of a shaft 31. This shafthas a gear 32 meshing with the pinion 30 so that the shaft 31 may be rotated from the sl'iaft Q6 and, if desired, held in an adjusted position. The shaft 31 adjacent each end thereof has secured thereto by means of a set-screw 33 the hub 34 of an eccentric 35. The eccentric 35 is provided in its outer surface with a groove 36 in which operate pins 3.7 extending through the eccentric 'strap 38. This eccentric strap has a pair of ears 39, the purpose of which will hereinafter appear.

The shaft has furthermore secured thereto a cable drum -lO having two cables d1 and i2 oppositely wound thereon. iin upper jourl` nal castingl is provided on each post -16. This journal collar is split and eared, as at 44, so that it may be secured in adjusted positions upon the postl and has projecting outwardly from one side thereof a journal -i-5 for the reception of a shaft 46 to which secured colla-rs l? operating in recesses 4:8 formed in the journals to prevent longitudinal movement of the shaft. Each upper journal casting has secured to one face thereof when in properly applied position an ear i9 having a vertically directed opening 50, this opening aligning with the eccentric 35 applied to the adjacent end of the shaft 31 and to the opposite face thereof an ear 51 having a horizontally disposed opening- 52 for the reception of a rod 53 having at its outer end a pulley 54- aligning with the drinn 40 of the shaft 31 for a purpose presently to appear.

The shaft d6 is longitudinally trussed, as indicated at 55, and has mounted thereon at spaced intervals channel supports 56 each having means 57 for receiving and clamping in position a transversely extending channel bar 58 and adjustable means for trussiug, generally designated at 59, for trussing such channel bar. AThe outer ends of the channel hars are connected by longitudinally extend- 'ment with the se'ven-eightlis of an ing bars 60 suitably trussed, as indicated at 61. The connections between the channel bar supports and the shafts 46 are adjustable and the connection between the bars 58 and 60 are likewise adjustable so that the size of the platform provided may be adjustably altered. Upon this platform is built the mold from which the "all is to be formed and in the buildingl of this mold, care is taken that the mold is'of less length than the side of the base to which it is applied, joints between the formed walls il being' obtained in a well known manner, generally illustrated in Figure 11. The frame built upon the shaft i6 and seating` on the irons 58 and 60 is provided at opposite sides thereof and at each end with means los attaching to the frame the end of the cables d1 and 42, as indicated at 62.

This frame is further provided with means whereby the ends of diverging rods 6? secured to the ears 3f) of the eccentric strap may be attached thereto. These rods, as indica-ted at G-l, are adjustable as to length and are intended to rock the mold platform after1 the charge is placed theiein. The cable connections are employed for rotating the platform about its axis and the arin 523 and pulley ad serve to engage the upper end of the cable as the platform is rotated and tension the saine during the rotatinn nievement. Means are further provided for connecting the molded wall to the frame formed by the rods 5S and 60. These means include supports carried by the frame and receiving' one end of an eye bolt 66, the eye o." which .is engaged over one end of the projecting'reinforcing rods 67 commonly einployed with the type of a wall jointin construction above referred to and illustrated .in Figure 11. These connections prevent slipping of the formed wall upon the mold as the mold is being tilted.

Tn setting up the frame, the posts 16 are bolted securely to the corners of the base. The lower castings 19 are placed upon the posts and then the upper castings d3 are so positioned on the posts that the distance from the top of the base to tlie top of the proposed framewill about equal one half the height of the wall to be molded. The purpose of this is the maintenance of the fran'ic as nearly as possible in a balanced position. The castings 56, 59 are then slipped upon the shaft d6, the collars 47 placed on this shaft and the shaft placed in position with the ends thereof journaled in the bearings 45. A' seven-eighths of an inch board is now laid upon the base between the posts, and the channel bars 58 slipped into the guides :n3 while in a vertical position and the ends of these channel bars are. brought into en,

inch board. They are then secured in position and while vertically disposed are in the `exlli) -Lseevos Vchannel bars 58 will provide a guide-indicating the proper position of the foot end of this mold.

The .mold is then partially ll-ed with cement. The rods 63 are'now employed with the eccentric n,strap to rock thefinold and, ifV desired, supports may be placed Vunder opposite sides of the mold against which the mold will be jarred as it is'rocked by these rods so that a thorough shaking up of its contents occurs yreleasing therefrom any trapped air permitting the cem-ent to cleanly and` smoothly engage against the vface of the ymold.A The reinforcing rods. are then placed in position in thefusual manner, :tlierod 66 engaged withone of these reinforcing rods, as above described, and the remaining ce- .ineiit placed in the, mold. lWhen the lconcrete hasset, itgis merelyI necessary tok employ the cables 41,42, for rotating the ystructure upon its axis yand the eccentric rod168 foi" lowering the. Wall invpos'ition upon the base. Before .the wall is dropped `to its lowerinost position, cement or a similarbinding agent may be placed between the base and the ylower face ofthe lwallfor bonding the same.

Itwill be obvious that yin` the vmethod above described, the mold, when in horizontal position, projects beyond the sides ofthe baseand it willvalso ybe obvious that this will sometimes be iinpossiblefdue `to presence of some obstruction adjacent the base.

`lllhere tliis'occurs, modified upper journal castingsare provided such as areillustrated in Figure 10. at 69. These castings are of the same construetion-asthe castings A`43with .the exception of the factthatthey are provided upon their outer endswith a cable receiving' eye 7 O and upon their lower surfaces with rollers 7l. ABefore theseupper journal castings are placed in4 position -upon the posts, each post of the pair is connected with the opposed post oftheother pair by a track 72 having agrooved upperfface 73,

in the `grooves of which theroll-ers 71 operate. This track has openings 74 at itsje-nds for the reception of the posts and is split and eared at its opposite ends` as indicated at 754 and 76,-so thatit may be clamped upon the posts. The ears at 76, in addition to providing .aineans for constricting the adjacent ends of the opening 74 to provide the clamping action, also serve to provide "a pivotal support for a cable guide pulley 77. rllhe outer faces of the trackshave formed thereon ears 78 for the reception of the eccentric rods 68 so that these tracks may be raised and lowered, after the manner of raising and lowering' the upper journal castings 48 above described.

In the use of this form of the device, the frame is built, as above described, and supported in the same manner from the journal castings 69 but after building the frame, the journals are moved to the center of the track so that t-he mold is positioned entirely over the base. This frame may then be moved to a vertical position and shifted longitudinally of the track by the connecting cable 41 or 42 to the ear 70 until the openings 79 of the journal castingsj69 align with the posts. The entire track is then lowered until the frame is properly positioned. The openings 74 of the track are elongated longitudinally to take care of a slight inisplaceiiient of the opposed post of the other pair. rlhe sheave 77 is preferably a double sheave so that tliesecond cable 4l or 42 may be attached to the' frame, as shown in Figure 8.

I am aware that it has been'heretofore proposed to support a frame from a base so that this frame may be rotated or vertically adjusted but all of these devices with which I ain familiar make no provision for agitating the frame or for compensating for interference by obstruction so that in event there is obstruction, they become inoperative. I do not wish to be understood as limiting myself to the specific structure hereinbefore set' forth' for this structure may obviously be modified to a certain extent without in any manner departing from the spirit of my invention.
